IMPROVEMENT IN CAPS OF BOXES AND BOTTLES.

Specification forming part of Letters Patent No. 130,086, dated July 30, 1872.

Specification of Improvement in Gaps of Boxes and Bottles or other vessels or receptacles containing powdered or liquid substances, the invention of WILLIAM L. TRoxELL, of Brooklyn, in the county of Kings and State of New York.

The invention relates to that class of box and bottle caps which are perforated for sprinkling, dredging, or pouring, and fitted with a revolving valve or register for opening and closingthe perforations. It consists in the combination with the valve or register of a per- ..manen tly-attached surrounding rim,which contains a female screw, and is so fitted to a male screw on the head, neck, or cover or stopper of the box or bottle that the valve or register by being turned to close the perforations is also screwed down tightly, and so made to close veryeffectually.

In the accompanying drawing, Figure 1 is a perspective view of a boxhaving a cover constructed according to my invention. Fig. 2 is a similar view of the cover detached from the box; and Fig. 3 is a view, likewise in perspective, of the valve or register Similar letters of reference indicate corresponding parts in the several figures.

A is the box, which is of ordinary construction and of cylindrical shape. lts cover B is of a size to fit its upper edge, and has formed on it a raised head, a, which is provided with a series of perforations, b b, and whose neck, 0, has formed on it, by spinning or otherwise, amale screw-thread. (J is the valve or register, which has formed in it a series of perforations, e 0, corresponding in number and position to those in the head a of the cover B, so that when arranged over those in the cover communication is opened to the box. This valve has provided on its under side a surrounding rim, f,

in which is spun or otherwise formed afemale screw-thread, which fits the male thread on the neck 0 of the head a on the cover B.

To open the box the valve is so turned that its perforations are over those in the head a of the cover B, and its contents may then be sprinkled or poured in the ordinary way. To close the box the valve is turned so that the perforations of the valve are intermediate to the perforations below them in the head of the cover. By means of the screw-threads, when the valve is turned to close the perforations in the box, it is drawn down tightly thereon, and so very effectually closes them. Valves thus secured to their caps or covers are less liable to become loose with wear than are those pivoted in place by a central pivot, and, owing to the stiffness imparted them by their rims, never become loosened by being sprung or bent and turned up at the edges, as those in common use.

When attached to bottles, jars, or other vessels for containing liquids, but one perforation need be provided in the cover and valve, and in such case the valve may befaced with India rubber, cork, or other soft elastic material.

Thisinvention may be manufactured of hard India rubber or other material as well as of spun metal.

Claim.

The perforated valve or register, provided with a screw-threaded rim, in combination with the screw-threaded neck of the head on the cover, neck, or stopper, substantially as and
